Western Chips in Russian Weapons: Microelectronics Found in Missiles & Drones
Every time a Russian Kalibr, Kh-101, Shahed-136 or Lancet is recovered in Ukraine, investigators open it up and find the same uncomfortable truth: Russia's precision weapons run on foreign microelectronics. Teardowns by Conflict Armament Research, the Royal United Services Institute and the KSE Institute have catalogued microprocessors, memory, signal processors and field-programmable gate arrays made by US, European and Asian firms. Russia cannot make these parts at scale, so it buys them through opaque intermediary networks. This page summarises what the open-source teardowns show, how the numbers should be read, and why a handful of cheap chips matter so much.
What the Teardowns Find
The picture that emerges across multiple independent investigations is consistent: Russian missiles and drones are built around commercial, off-the-shelf microelectronics rather than exotic domestic silicon. RUSI's landmark 2022 report, Silicon Lifeline, found more than 450 distinct foreign-made components across recovered Russian systems, including digital signal processors, flash-memory modules and static-RAM modules attributed to US firms such as Texas Instruments, Advanced Micro Devices and Cypress Semiconductor, alongside Ethernet cabling traced to American, Dutch and German companies (RUSI, 2022).
Conflict Armament Research, which physically documents materiel on the ground in Ukraine, reached similar conclusions in its analyses of Iranian-designed drones used by Russia: the overwhelming majority of the electronic components originated with US companies, with the most frequently recovered microprocessors attributed to Texas Instruments, Analog Devices and the former Maxim Integrated Products. None of this implies wrongdoing by the manufacturers, who say they comply with sanctions and have halted Russian sales; the parts are mass-market goods that change hands many times.
The throughline is that Russia's war machine depends on a relatively small set of critical, widely available chips. That dependence is what makes the teardown work strategically useful: it identifies exactly where pressure could bite.
Components by Weapon System
Different systems carry different parts counts, and the figures below are illustrative snapshots from published investigations rather than fixed bills of materials. The Kh-101 cruise missile, used in strikes on Kyiv, was reported by RUSI to contain 31 foreign components; across 27 weapons systems including the Iskander and Kalibr, RUSI catalogued 208 unique components produced by 10 companies.
| System | Type | Reported foreign content (illustrative) |
|---|---|---|
| Kh-101 | Cruise missile | ~31 foreign components (RUSI sample) |
| Kalibr | Cruise missile | DSPs, memory, signal-processing parts |
| Iskander | Ballistic missile | Microprocessors from US makers |
| Kinzhal | Air-launched ballistic | Western/Asian microelectronics reported by GUR |
| Shahed-136 / Geran-2 | Loitering drone | Components attributed to ~12+ firms, multiple countries |
| Lancet | Loitering munition | Xilinx/AMD FPGA for image processing |
⚠ Counts are approximate and sample-dependent. Sources: RUSI Silicon Lifeline; Shahed component investigation; Kyiv Post / HUR. Not investment advice.
For loitering munitions the FPGA story is especially telling. Public Lancet teardowns repeatedly identify a Xilinx (now AMD) field-programmable gate array handling onboard image processing and target recognition. FPGAs are prized because designers can reprogram their logic without commissioning custom silicon — a capability Russia struggles to replicate domestically, which is exactly why such parts keep reappearing.
Who Does the Investigating
Four bodies dominate the open-source record. Conflict Armament Research (CAR) documents recovered materiel in the field, photographing markings and tracing chips back through distribution chains. RUSI produced the influential Silicon Lifeline framework that classified which components are most critical and hardest to substitute. The KSE Institute at the Kyiv School of Economics has published detailed papers on foreign components in Russian drones and on the trade flows that supply them (KSE Institute, 2023).
Ukraine's military intelligence (GUR) has gone furthest on volume, publishing a forensic database naming thousands of distinct foreign parts found across recovered weapons and exposing the full teardowns of major Russian systems. Reuters, OCCRP and other outlets add reporting and corroboration, while SIPRI provides the broader arms-trade context. Each of these sources is careful to flag the limits of its data.
How the Chips Reach Russia
The manufacturers do not sell to the Russian military. Instead, commodity microelectronics move through long, deliberately obscured chains: authorised distributor, reseller, trading company, and finally a front importer that fronts for a Russian defence buyer. Transshipment through third countries — Hong Kong and mainland China above all, but also the UAE, Turkey and Central Asia — is the standard means of circumventing Western export controls, frequently using false end-user declarations.
The economics favour the evader. These chips are cheap, produced in enormous volumes, and sold through countless channels, so once a lot leaves authorised distribution it is extremely difficult to trace. A reseller in a third country can legitimately buy parts and then divert them, and the original maker may never know. That is why investigators emphasise networks and intermediaries rather than the manufacturers themselves. We cover those networks in depth on our sanctions-evasion networks and China dual-use suppliers pages.
Why a Few Chips Matter
It is tempting to dismiss a handful of voltage regulators or signal processors as trivial. The opposite is true. Russia can build airframes, warheads and rocket motors domestically, but it cannot mass-produce the precision microelectronics that turn a projectile into a guided weapon. That makes a small set of critical chips a genuine chokepoint in the entire Russian missile and drone enterprise.
This is why teardown work has policy weight. By identifying which specific parts recur and through which intermediaries they flow, investigators give governments a targeting list: the components worth interdicting and the front companies worth sanctioning. The aim is not to halt every chip — that is impossible — but to raise cost, slow production and force inferior substitutions that degrade weapon reliability and accuracy over time.
Data Limitations
Several caveats apply to every figure on this page. Samples are biased toward weapons that were recovered, which over-represents systems used in failed or intercepted strikes. Attributions evolve as Russia substitutes suppliers, so a chip dominant in 2023 teardowns may be replaced by 2026. Headline counts — for example reports that a single large strike involved hundreds of weapons carrying tens of thousands of foreign components — are aggregate estimates, not audited inventories.
None of this undermines the central, repeatedly verified finding: foreign microelectronics remain embedded throughout Russia's precision arsenal, and the networks supplying them have adapted to sanctions rather than collapsed. Read the original reports for the precise weapons sampled and dates, and treat any single number as indicative rather than definitive.
Frequently Asked Questions
What foreign chips have been found inside Russian missiles and drones?
Teardowns by Conflict Armament Research, RUSI and Ukraine's GUR have documented microprocessors, digital signal processors, flash memory, static RAM, FPGAs and Ethernet transceivers from Western and Asian makers. Frequently cited names include Texas Instruments, Analog Devices, the former Maxim Integrated and Cypress Semiconductor, plus AMD/Xilinx FPGAs in loitering munitions. Counts are approximate and depend on the sample of weapons recovered.
How many foreign components are in a single Russian weapon?
It varies by system. RUSI's 2022 Silicon Lifeline report found 31 foreign components in a Kh-101 cruise missile and 208 unique components across 27 systems including Iskander and Kalibr. Ukraine's GUR later catalogued thousands of distinct foreign parts across many recovered weapons. These figures are sample-dependent snapshots, not fixed bills of materials.
Which chips are in the Shahed-136 drone?
Investigations into the Iranian-designed Shahed-136 (Russian Geran-2) have identified components attributed to roughly a dozen-plus companies across the US, Japan, Canada, Switzerland and elsewhere, spanning microprocessors, semiconductors, memory and signal-processing parts. Exact attributions vary between teardowns and over time as Russia substitutes parts. See CAR and KSE Institute reporting for documented lots.
What chip is in the Lancet loitering munition?
Public teardowns of the Lancet have repeatedly identified a Xilinx (now AMD) FPGA used for onboard image processing and target recognition, alongside other commercial microelectronics. FPGAs are valued because they let designers reprogram logic without custom silicon, which is hard to replace under sanctions.
Do the chipmakers sell directly to Russia?
There is no evidence the named manufacturers sell directly to the Russian military, and the companies cited in these reports say they comply with sanctions and have halted sales to Russia. The parts are commodity, dual-use microelectronics that reach Russia through distributors, resellers and third-country intermediaries, often years after original sale.
How do these chips reach Russia despite export controls?
Most documented flows run through transshipment and parallel imports: orders are routed via front companies in third countries such as Hong Kong, mainland China, the UAE, Turkey and Central Asia, with false end-user declarations. Because the parts are cheap, widely sold and hard to trace once they leave authorised distribution, interdiction is difficult.
Who investigates foreign components in Russian weapons?
The main open-source investigators are Conflict Armament Research (CAR), the Royal United Services Institute (RUSI), the KSE Institute at the Kyiv School of Economics, and Ukraine's military intelligence (GUR), which has published large component databases. Outlets such as Reuters and OCCRP and bodies like SIPRI add context. Each notes data limitations.
Are these chips advanced or off-the-shelf?
Most are commercial, off-the-shelf microelectronics rather than exotic military silicon: general-purpose microcontrollers, memory, signal processors, voltage regulators and FPGAs. That is precisely the problem — they are mass-produced, cheap and sold through countless channels, which makes a small number of critical parts very hard to choke off.
Has the volume of foreign parts in Russian weapons fallen?
Sanctions and export controls have raised costs and forced substitution, but investigators still find large numbers of foreign components in weapons recovered in 2025. Ukraine has reported strikes involving hundreds of weapons carrying tens of thousands of foreign-made components, indicating procurement networks adapted rather than collapsed.
Where can I read the original teardown reports?
Primary sources include CAR's online dispatches, RUSI's Silicon Lifeline report (2022), KSE Institute component papers, and Ukraine's GUR War & Sanctions database. Always check the publication date and the specific weapons sampled, since attributions evolve as Russia changes suppliers. This page is investigative analysis, not legal or investment advice.
